So how do i so how do I solve to get this answer

Elina [12.6K]

Step-by-step explanation:

First, You would solve what you can which would be the equation on the left Which will get you 4096. After that its just solving for P

4096=(4^p)^2

64=4^p (you would take the square root of 4096 to get 64)

Then, Since 64 is a perfect Cube root of 4, P will equal 3

The heights of women in the USA are normally distributed with a mean of 64 inches and a standard deviation of 3 inches.

Rainbow [258]

Answer:

(a) 0.2061

(b) 0.2514

Step-by-step explanation:

Let X denote the heights of women in the USA.

It is provided that X follows a normal distribution with a mean of 64 inches and a standard deviation of 3 inches.

(a)

Compute the probability that the sample mean is greater than 63 inches as follows:

$P(\bar X>63)=P(\frac{\bar X-\mu}{\sigma/\sqrt{n}}>\frac{63-64}{3/\sqrt{6}})\\\\=P(Z>-0.82)\\\\=P(Z$

Thus, the probability that the sample mean is greater than 63 inches is 0.2061.

(b)

Compute the probability that a randomly selected woman is taller than 66 inches as follows:

$P(X>66)=P(\frac{X-\mu}{\sigma}>\frac{66-64}{3})\\\\=P(Z>0.67)\\\\=1-P(Z$

Thus, the probability that a randomly selected woman is taller than 66 inches is 0.2514.

(c)

Compute the probability that the mean height of a random sample of 100 women is greater than 66 inches as follows:

$P(\bar X>66)=P(\frac{\bar X-\mu}{\sigma/\sqrt{n}}>\frac{66-64}{3/\sqrt{100}})\\\\=P(Z>6.67)\\\\\ =0$

Thus, the probability that the mean height of a random sample of 100 women is greater than 66 inches is 0.

Freddy is two years old than her brother. Twelve years ago, she was twice as old as he was. How old were they? Equation

Hitman42 [59]

F=2+b
12 years ago
f-12=2(b-12)
f=2+b
2+b-12=2(b-12)
b-10=2b-24
minus b both sides
-10=b-24
add24
14=b

14-12=2
2+2=4

freddy was 4 and brother was 2
they are now 16 and 14
